I recently beat one. 80 in a 70mph zone. Blind sweeping left on a divided hiway, instant on radar (Ka), no other traffic. My radar detector (cheap Bel) and I saw the cop at the same time. I filed for discovery just on the chance there may have been something lacking in the paperwork - the state failed to prove the radar gun used was a doppler device - case dismissed. mike miller 91 200q
